So, here’s a request:
A wealthy mother…someone prominent in the community…and her young son enter a bank to attend to some of her accounts.
During their visit, the bank staff and the other visitors find themselves held hostage in a robbery by a gang of gun-toting thieves.
As the crooks are tying up the security guards, staff, and visitors; one of them recognizes the wealthy mother, and they realize she’ll make a particularly valuable hostage.
They tie & gag her son so that she’ll cooperate, and as the bank robbers communicate with police, they use the wealthy mother as the person who talks to them over the phone, telling her what to say.
After they finish negotiating their getaway with the loot, they tie & gag the mother, and take both her and her son with them in their getaway vehicle.
They then reach an unknown location, and swap the money into another car, leaving the mother & son tied and gagged in the back of the now-empty van for police to find.
Bindings should be ropes.
For gags, I like white tape gags…and then cloth OTM gags. : )
